    • A device and method for verifying the integrity of a memory in a remote device are provided. An exemplary memory integrity verification method compares, based on a verification parameter received from a verifier, the time for retrieving data block of a memory of a remote device with a maximum threshold time allowed to read the memory, and transmits to the verifier a remote verification code and a data status according to the result of comparison so that the verifier can verify the integrity of the memory. Instead of relying on the verifier, the remote device provides data status information for integrity verification by using the memory retrieval time. As a result, accurate integrity verification is provided, and no independent hardware is required to verify integrity.
